I need to confirm if fragments are supported on cloud service give me a day or two to get back to you on this

the command for creating cloud service project is like thismvn -B archetype:generate -DarchetypeGroupId=com.adobe.aem -DarchetypeArtifactId=aem-project-archetype -DarchetypeVersion=41 -DaemVersion="cloud" -DartifactId="aem-banking-application" -DappTitle="BankingApplication" -DappId="bankingapplicat...

If there is no cloud service in the url it’s not for cloud serviceIt’s for 6.5, I have sent you a link for cloud service document generation 

the link you are following is for 6.5.It will not work for AEM Forms Cloud Service

For AEM forms cloud service it’s a little different to create your projectplease follow the documentation on creating AEM project for cloud service The way you generate documents on cloud service is different from AEM 6.5

There are API exposed that allow you to merge data with template on cloud servicerecommeded to use those API  

How did you create your AEM project?

Can you please let us know what steps have you followed so far?

I don’t think you  use that package on cloud service AEM formsTo use output service in AEM forms cs, you will have to make a post call to rest api to generate documents
